Application filed July .6, 1865. Serial No. 269,843.

To (LN whom, it may concern:

Be-it known that I, FRANCIS W. H. CLAY, a citizen of the United States,residing at Pittsburg, in the State of Pennsylvania, have inventedcertain new and useful Improvedrawings; but the principles of itsoperation are applicable to many other forms.

Figure 1 is an under plan of a metallic cap in its normal conditionbefore application to the bottle. Fig. 2 is a top plan of a bottlehcadwith the same cap fixed thereon to close themouth. Fig. 3 is a centralvertical section of the bottle-head and the cap before the ca 3 issprung into place on the head. Fig. 4 is Hill a side elevation and halfa central vertieal section of the bend and cap together, as in Fig. 2.Figs. 5 and 6 are sections of ahead and a modilicd form of closing-capthereon, respectively, before and after the cap has been distorted tobring pressure on the pack ing. Fig. 7 is a top plan, and Fig. 8 is aside elevation, of the same form of cap innormel condition. Figs. 9 and10 are central vertimll sections of another form of the cop andboLthE-heaul, respectively, before and after distorting the cap to bringpressure on the pan-king, as ex planied hereinafter.

licretohire the necessary pressure between the peeking and the mouth ofthe bottle have been supplied by the packing itself, which musttherefore be elastic. The metal holdingr devices were only for thepurpose oi keeping the cork or rubber in place to exert their elasticpressure. A former patent granted to me, No. 755,276, Mart-i122, 1904,covers the idea of supplying the pressure by the cap itself. liigs. lto4heroin show adeviceinvolving' this idea, as also some features setforth in my copending application, Serial No. 239,593, filed January 4,1904, and further improvement thereon. The bottle-head 11 has ananchorage-ledge 12, and in this case a fiat top. The cap comprises theclosing part or plate 13, which is bordered by an indented annular rib14 to make sharp contact with the top and to prevent distortion of theplate. Extending from the plate 13 are resilient arms 15, which areflat, so as to bend readily and he s n'ingy. Attached to them aredecnding 16, connected at their ends or liottoms by a corrugated flangeor narrow ring 17, so arranged as to project under the ledge 12 oi thehead when the legs lie against it and being of less diameter than thehead, so that it automatically snaps under it when the ca 1 is'presscddown. (See Fig. 3.) The parts lieing in the position of Fig. 3 and anoiled-paper peeking-disk 18 being placed over the mouth of; the bottle,the tops of lhe arms 15 are pressed down by a flat surface, which thusengages their ends, the ring 17 snaps over the anchorage-ledge, at thesame time forcin r the legs 16 outward, increasing the an lc )etwecnthem and the arms 15. In the C position of Fig. 4 the effort of theresilient arms to rise to normal position again presses the bead or rib14 tight down on the disk 18, making the seal, and the effort of theparts to resume the normal angle between the arms and legs kce )S thecorrugated ring 17 close under the in go 12. The fixing of the cap inplace is thus automatic, and the legs 16 are guarded and hold by theirown rigidity, it being noted that they are parts of a cylinder in form.This form of cap is easily made in a die at one operation, and the formof the ring 17 enables it easily to fit irregular bottle-heads.

In Figs. 5 to 8 is shown a form of the cap iii-which while theengagement of the anchorage-ring 1'?" is automatic, as hefore, the dis-.

tortion of the dl'lEtELlllC connection between the legs 16 and theresilient arms 15 is done by a separate operation. by any convenienttool which )resses together the sides of the bond 20. he cover-plate 19may have the rib thereon when desiredybut it is not so necessery in thiscase, as the arms 15 are flat and in line with the top 19, and thebending does not endanger the ht on the bottle.

In Figs. 9 and 10 the cap is modified to use on a more common form ofbottle -hcad. The head 21 has a rounded top edge 22 and ananchorage-ledge 12. The on may have an upw ardly-indented rib or bear23, formed to approximately lit this edge, and a iaper' packing-disk 18is placed between in on or to take up any unevenness of fit. (This couldbe wax or gain, as it need not be elastic.) From the head 23 thereextends a folded or bent part 15", which may be solid or in the form ofarms, as in Fig. 4, and the dependi legs 16. may be connected by acorrugat dil the ring 17 besides by ring 17, as before, though othermeans of anchorage ma be used. When the cap has been pressed dbwn on thehead, as in Pig. 9, so that the legs are anchored under the ledge 12,some tool, such as an annular vise, or any two ressure-surfaces, as A A,are applied to pine together the bend of the part 20, connecting thering 17* and the top. This causes the distortion shown in Fig. 10, bywhich the top and anchorage parts are resiliently forced together,inducing the desired pressure on the disk 18.

The various advantages of these devices will readily occur to thosefamiliar with the art.

Having thus described my invention and illustrated its use, what I claimas new, and desire to secure by Letters Patent, is the followin 1. In abottle-closure, in combination with a bottle-head having an anchoragethereon, a cap comprising a part covering the bottlemouth, a corrugatedring engaging the anchorage, and a connection between said two partsresiliently drawing them together to exert self-induced ressure of thecap itself upon the bottle-mout 1.

2. The combination of a bottle-lmad having an anchoragededge with aclosing-cap thereon comprising a cover-plate, a resilient expansiblering engaging the ledge and bent portions connecting the plate and ringand resiliently ressing them toward each other, substantia y asdescribed.

3. In a bottle-closing cap, the combination of an expansible rin adaptedto snap over and engage the hea of the bottle, a coverplate for themouth of the bottle, and resilient bent members connecting the ring andplate, adapted to be sprung out of normal po sition in application,whereby the plate is drawn down and the cap exerts self-induced pressureon the bottle-mouth to close it. i

4. A bottle-closin cap comprising a cover having spring-arms, egsdepending from said arms, and a ring connecting the ends of said legsand adapted to engage the head of the bottle.

5. A bottle-closing cap comprising a cover having resilient arms, le sdepending from the arms, and an cxpansi )le ring connecting the arms andadapted to automaticallv engage the bottle-head and by means of said egsto hold the arms sprung out of normal position in application.

6. A bottle-closing cap comprising a cover part, an anchorage partadapted to engage the bottle-head, and a bent part connecting the coverand anchorage part, adapted to have the sides of its bend sprung out ofnormal position in. a plying the cap, to thereby resiliently draw t 10cover and anchorage t ether and exert pressure of the cover on t ebottle-mouth. I

7. A bottle-elosing cap comprising a part adapted to engage and fastenon the head, a closing cover part for the mouth of the bottle, andresilient meinbcrs connecting th said cover and anchorage parts adaptedto become pressed so as to draw said parts together and exert resilientpressure on the bottle-mouth, whereby no elastic packing is re uired.

8. The combination with a ottle head having an anchorage-led c, of aclosure com prising a rin engaging t e ledge, a cover for the month 0the bottle, and parts connecting the ring and cover formed of bentresilient metal and adapted by compression of the bend to draw down thecover toward the anchorage, to make the seal.

9. In a bottle-closure, a cap adapted to it over the bottle-head andhavlng means to engage the head so as to be retained thereon, and acover for the bottle-mouth, bent members connecting the said cover partto the engagi ng means and the bend adapted to be co pressed to shortensaid connecting memls and thereby press the cover down on the lttle-mouth.

10. In a bottle-closure the combination with a bottle-head having anoutside retaining-ledge, of a cap having a cover for the mouth of thebottle, a part engaging said retaining-ledge, and resilient bentportions connecting the cover and retainin r part and adapted to becompressed in or er to draw the cover down on the bottle-mouth.

In testimony whereof I have hereunto signed my name in the presence ofthe two subscribed witnesses.
